QDL/QDLF 為安裝標準電機的非自吸式多級離心泵，電機軸通過泵頭用軸聯器直接與泵軸連接，拉桿螺栓將耐壓筒、過流部件固定在泵頭和進出水段之間，泵進出水口在泵底同一直線上；本泵可根據需要配置智能保護器，對泵干轉、缺相、過載等進行有效保護。

QDL / QDLF for the installation of a standard motor non-self priming multistage centrifugal pump, the motor shaft through the pump head shaft associated with the device connected directly to the shaft, rod bolts will pressure cylinder, fixed flow components out of the water in the pump head and paragraphs between the pump inlet and outlet of the pump at the end of a straight line; the pump may need to configure the smart protector, dry running of pumps, phase, effective overload protection.
